What is the chemical formula for magnesium bromate?

これを理解する方法は次のとおりです。

* マグネシウム is a Group 2 element, meaning it has a +2 charge (Mg²⁺).

* Bromate is a polyatomic ion with the formula BrO₃⁻ and a -1 charge.

* To balance the charges, you need two bromate ions (2 x -1 =-2) to neutralize the +2 charge of magnesium.

Therefore, the formula is Mg(BrO₃)₂ 。
